For a mobile phone with a built-in battery, the mobile phone is generally designed to be restarted after being pressed for 10-20 seconds, but a user often does not read a use instruction in detail, and after the key is not reacted and the power key is pressed to turn on or off, the mobile phone is easy to be damaged and cannot be started, complaints and complaints are generated, and the user experience is poor. Therefore, there is a need for a method of automatically detecting a crash anomaly and restarting.
At present, there are three methods for restarting due to crash: the first is to realize hardware reset or power off by setting a special switch key structure.
